Resolution
Resolution refers to the shape of the captured area in pixels. It represents the number of pixels
enabled to capture an image. For example, if 800x600 is set the full sensor space available it
is called “Full Frame.”
The Resolution setting allows the user to change the dimensions, or aspect ratio, of the
sensors active pixel area. The aspect ratio is the width to the height ratio of the image being
recorded. Each type of camera has a specific maximum resolution.
Changing the Resolution settings to match the dimensions of the subject of interest allows the
user the option of recording at higher sample rates, or longer recording times at the same
sample rate. Smaller resolutions ‘crop’ the capture image by enabling a subset of pixels, this
allows you to customize the shape of the capture area to the application. For example, if you
are capturing a linear environment such as a rocket car, you do not need to capture the static
sky above and ground below the subject.
Sample Rate
The Sample Rate is the rate at which images are recorded. The Sample Rate field selection
list will change according to the Resolution selected. The larger the selection area the lower
the maximum frame rate.
NOTE
Set the Resolution before setting the Sample Rate. To set high sample rates, or increase the
recording time, reduce the selected Resolution (Width x Height).
Shutter Angle
Adjusting the shutter angle affects the amount of time that sensor is exposed to light. A larger
shutter angle may result in an increased motion blur on moving objects.
Post Trigger (via Memory Buffer Graphical Display)
The Post Trigger value represents how many pictures will be recorded after the trigger signal
is detected by the Phantom camera.
NOTE
Since the Phantom CineMag memory is a linear memory buffer, the Post Trigger value will
be automatically set to 1.
Maximum Recording Time
This field indicates the length of recording time left. The recording duration is based on the
amount of memory in the camera, along with the resolution and frame rate settings. This field
will change based on these variables. As takes are recorded the Total Time Available will
decrease in real time.
Maximum Recordable Frames
This field indicates how many images or frames can still be recorded into the Phantom
CineMag. As takes are recorded the Total Frames Available will decrease in real time.
